I'm definitely not renewing my sub after the promo. One of the main reasons is that DLCs of game pass games are not included so I feel like I don't get the full experience. I would rather wait and buy the version that includes all the DLC at a discounted price that is mine forever.
I will definitely be renewing mine, I understand what you mean about DLC but for me its all about the games that I get with Gamepass which I would absolutely never had bought normally. Stuff like Void B*****ds , Dead Cells, Gears 5 , Forza 4 and so on, theres no way I would have put my hand in my pocket and bought any of those and yet I've had a lot of fun with them and I'm sure there will be many more down the road which will turn out to be unexpected fun to me which I'd never have bought.
